12 And this land which we took at that time, from Aroer by the valley of the Arnon, and half the hill-country of Gilead with its towns, I gave to the Reubenites and the Gadites. 13 The rest of Gilead and all Bashan, the kingdom of Og, all the land of Argob, together with Bashan, I gave to the half-tribe of Manasseh. (This land is named the land of the Rephaim. 14 Jair, the son of Manasseh, took all the land of Argob, as far as the country of the Geshurites and the Maacathites, naming it, Bashan, Havvoth-Jair after himself, as it is to this day.) 15 And Gilead I gave to Machir. 16 And the land from Gilead to the valley of the Arnon, with the middle of the valley as a limit, as far as the river Jabbok which is the limit of the country of the children of Ammon, I gave to the Reubenites and the Gadites; 17 As well as the Arabah, with the river Jordan as their limit, from Chinnereth to the Salt Sea, under the slopes of Pisgah to the east.

Commentary on Deuteronomy 3:12-20
(Read Deuteronomy 3:12-20)
This country was settled on the Reubenites, Gadites, and half the tribe of Manasseh: see Numbers 32. Moses repeats the condition of the grant to which they agreed. When at rest, we should desire to see our brethren at rest too, and should be ready to do what we can towards it; for we are not born for ourselves, but are members one of another.
